The study "Evaluation of Conservation efforts to prevent the extinction of the Iberian lynx ', produced by a team of researchers from the Department of Conservation Biology, Doñana Biological Station, Institute of Research Council for Scientific Research (CSIC), says the lynx "may be the first cat to become extinct in a developed country because what happened in the species for 25 years so far, have disappeared in eight of the ten villages that existed on the peninsula, so indicate. "
Francisco Palomares, one of the authors of the article, he told Europa Press that all the cats that exist at present is the species that is "most at risk of extinction." Also, the paper published in the journal Conservation Biology, "the best scientific publication specializing in conservation," is based on a review of the status of lynx populations for over 40 years and working for 20 years with the reality of lynx conservation. "The story of what has happened so far is to be extinguished, as they have disappeared in eight of the ten stocks in which there was 25 years ago, and the other two, one of them, the numbers have declined more than 80 percent, "he assured.
Palomares, which produced the study along with researchers Alejandro Rodríguez, Eloy Revilla, José Vicente López and Javier Calzada, recalled that 25 years ago the International Union for Conservation of Nature (IUCN) found that the Iberian lynx was the kind of cat "at greater risk of extinction in the world." Then, as explained, is estimated that more than 1,100 copies were distributed in ten different populations distributed in the southwest quadrant of the Iberian Peninsula.
In this regard, he pointed out that this situation alarms triggered regional, national and international, although 16 years later, in the period between 1985 and 2001, general distribution and abundance of lynx have decreased between "86 and 93 percent, and eight of the ten stocks that had been extinguished. " In addition, he stressed that currently "there are only about 200 individuals released survivors in these two populations.
also noted that the size of the population of lynx in the Doñana Natural Area "has remained around 50 copies for the past 25 years, and its persistence over time depends mainly on the number of territories situation exists within the national park. "Between 1985 and 2005, the number of territories in the park" was reduced from eleven to five, which increases the probability of extinction of this population from 34 percent to 95 percent, "he stated.
however, stressed that" spatially explicit models based on the individual show that extinction Doñana population could be avoided if ten new territories were established in the park and released 14 individuals, preferably from the population of Sierra Morena, for a period of 5 years. "Moreover, the available data" do not quantify probability of extinction of the lynx population in the Jaén population, although between 1985 and 2005 this population showed a similar contraction pattern in other populations that are already extinct, decreasing by more than 80 percent, "he reported.
On the other hand, Palomares stated efforts have been made "clear" of conservation in at least four of the ten identified lynx populations 25 years ago. However, in two of these populations, particularly Malcata (Portugal) and Montes de Toledo lynxes have become extinct, and the other two in Andalusia, "your chances of extinction increased between 1985 and 2005."
"significant efforts in DOÑANA"
The most important conservation efforts have been made in the Doñana lynx population, which since 1986 have made more than 19 projects for the conservation of the species by the central government and the Ministry of Environment of the Junta de Andalucía, "thanks to the number of copies has not diminished even further," ay other agencies, which involves an investment in Spain over 60 million euros in the last 30 years.
however, pointed to Europa Press that although there is plenty of scientific information and have made significant conservation efforts, "the Iberian lynx is extinguished." In this regard, said the study points to four aspects that could explain the "limited" success of conservation. So often indicates that conservation measures have been implemented in areas "very small, although to house a population with little chance of becoming extinct" would require a surface quality of the habitat of at least 500 square kilometers. "
It points which have been used" few resources to the scientific monitoring of the effectiveness of conservation actions, which is not allowed to perform an adaptive approach based on scientific evidence. "The third point is" lack of continuity in the recovery effort because, among other things, to limit to 4 or 5 years on charges of policy makers, and the rigidity of the conservation plans that do not allow adaptive management mentioned above.
Palomares
also indicated that conservation managers have "little confidence" in scientific knowledge, sometimes just being taken into account "when it is too late to act." In this regard, said that the need for reintroduction programs in areas where lynx had become extinct was recommended more than 10 years, but had to wait until 2009 to be carried out for the first releases of lynx.
Furthermore, the researcher of the Doñana Biological Station indicates that the reasons that make it go away are several, but in the circumstances the principal is that "there are very few individuals and populations, and the lack of rabbits and loss habitat, among others.
Palomares has stated that the article does not present solutions for recovery, but suggestions that conservation efforts are being made to be truly effective. "In conclusion, ensures that the conservation of species as the Iberian lynx must be based on scientific knowledge and conservation plans large-scale spatial and temporal including monitoring of the actions performed by agents outside agencies that perform management actions.
